Cardiff & the Coke Ovens

Why Cardiff?
In September of 1887, the Grand River Coal and Coke Company selected Cardiff, four miles south of Glenwood Springs, for their coal coking ovens. The coal for the ovens came from mines to the south at Marion, Spring Gulch, Jerome Park and Sunlight—places now all but erased from the face of the earth. By December, the town site was established, and the Colorado Midland Railroad was built to Cardiff. That same year the first 50 brick coke ovens were constructed. In January of 1888, the first coal was delivered, and the
ovens fired. 


 

What do silver and coal have in common?
In the 1880’s, silver ore mined near Aspen could not be smelted without high-quality bituminous coal which is “coked,” or heated to extremely high temperatures in beehive shaped ovens to remove impurities.
Steel making also requires coked coal. 

 

Here Yesteryear, Gone Today
Cardiff, named after Cardiff, Wales grew into a thriving community of 150 people with miners from as far away as Italy and Wales. It had employee houses, two bunkhouses, a school, hotel, several mercantile establishments, a four-stall engine house, a section house, blacksmith shop, cattle pens and a wye. Imagine the incandescent glow of the ovens at night with smoke continually shrouding the community.

 

Colorado Fuel and Iron Company (C.F. & I.) dominated the region’s coal mining industry and took over the ovens in 1892, producing 65,000 tons per year by 1895. Coke production remained strong into 1900 but demand fell steadily until 1915 when the ovens were closed for good causing the decline of the town into oblivion over time.
In 1934, the town site and ovens were purchased by George Sumers, a New York investment banker. George built his summer home, a large log lodge, near Cardiff, using stone from the coke ovens for the lodge’s foundation and fireplace. The entrance to Glenwood Park’s homes to the north of Cardiff was also built from the oven’s stone facing as seen in the photo above.
The march of progress has destroyed most of the 240 ovens. Thanks to donors Kenneth Balcomb, Robert Delaney and Pete Waller the Glenwood Springs Historical Society owns the remaining 54 ovens which on the National Register of Historic Places.

Looking north toward Glenwood Springs where the Colorado Midland Railroad cars loaded coal onto horse-drawn carts across tracks located on top of the ovens. Coal then dropped into the ovens through an opening where it was ignited. The doors in front controlled access to the finished product—coke, a fuel that burned hotter and cleaner than coal and is shown in piles awaiting shipment on the Colorado Midland RR tracks which are to the right and out of picture (photo by William Henry Jackson, courtesy History Colorado-Denver, Colorado; negative 86.200.7052)
